Tech blog Pocket-lint says one of its "trusted sources" revealed that Facebook is trying to buy Opera Software, the company behind the Opera Web browser, a sign that the social-networking company might be looking to launch its own browser.

The move would put Facebook in competition with other tech companies in the browser game -- including Yahoo, which recently launched Axis, and Google, which has already released extensions to integrate its social-networking component, Google +, into its browser.

Pocket-lint speculates that a Facebook browser "would allow you keep up to date with your social life from in-built plug-ins and features on the menu bar."
